Installation situation

There are three options for installing backwater protection.

Outdoor, underground

installation

This is the most practical solution.

Products to protect against

water ingress are installed in a

chamber in the ground in front of

the building. This saves space in

the basement, noise nuisance can

be practically ruled out and the

installation is functionally secure

and maintenance-friendly.

Types of wastewater

In principle, we differentiate between

two different types of wastewater.

Different backwater protection

devices can be considered depending

on the type of wastewater being

dealt with.

Exposed installation

This is the simplest solution as

it does not require a great deal

of structural rework. This means

that the installation is quick and

that the backwater protection

unit is always easily accessible

for maintenance and cleaning.

Floor slab installation

This is the most convenient solu-

tion. With floor slab installation,

the backwater valve takes up no

living space as it is unobtrusively

installed in the underfloor.

However, it is still accessible for

maintenance or repair via the

cover. Ideal for new construction.

Wastewater with sewage

is water with faecal content

coming from urinals or toilets

to the sewer. This is termed

"black water".

Wastewater without sewage

is water without faecal content,

for example shower water or

water from a washing machine.

This is termed "grey water".
